• Locate the idle running speed adjustment screw (40) behind the
air filter casing (5) (fig. N).
• Start the grass cutter engine.
• Use screwdriver to carefully turn the idle running speed
adjustment screw (clockwise to increase speed, counter-
clockwise to reduce speed).
INSTRUCTIONS REGARDING SAFE USE
• When cutting high grass perform the work gradually, by layers.
• Keep the petrol grass cutter away from hard objects and
cultivated plants.
• Operate the petrol grass cutter only when the grass is dry.
• When trimming edges drive the tool along lawn edge.
• Clean ventilation holes in engine casing regularly.
• Regularly remove grass residues from the shield and cutting line
spool.
• Never clean the petrol grass cutter with water, aggressive fluids
or solvents. Clean the petrol grass cutter with brush or delicate
cloth.
• Regularly check technical condition of the ignition plug of the
combustion engine. Replace worn out ignition plug with a new
one recommended by the manufacturer.
• Use recommended spools with cutting line.
PULLING OUT THE CUTTING LINE
The petrol grass cutter is equipped with cutting line feed system.
The cutting line will be pulled out when the spool is firmly pressed
against the ground. Excessive cutting line will be cut off with
blade located in the shield.
In case the cutting line is torn off or its part is broken inside
the spool cover, the cutting line will not be fed. In such case
pull the cutting line by hand.
PULLING OUT THE CUTTING LINE MANUALLY
Switch off engine of the petrol grass cutter.
• Use hexagonal key to lock spindle lock hole (23) (fig. E) and
unscrew cover of spool with cutting line (15) (fig. B).
• Hold spool cover firmly.
• Press in safety catches (18) (fig. C) at both sides of cover of the
spool with cutting line.
• Remove lid from the cover of the spool with cutting line.
• Put in ends of the cutting line and thread them through cutting
line holes (21) (fig. D).
• Install lid of the cover of spool with cutting line.
• Screw cover of spool with cutting line onto spindle.
Be very careful when using petrol grass cutter for vertical
trimming of edges. Stay away from the plane of cutting
element rotation to avoid risk of being hit with an object
projected by the cutting element.
Engine is very hot during operation and just after. Touching it
may cause skin burns.
Exhaust gases contain carbon monoxide, which may cause
poisoning when inhaled. Therefore never start the tool
indoors, in places with poor ventilation or close to flammable
materials.
OPERATION AND MAINTENANCE
Ensure the engine is switched off and is cold before cleaning,
checking or repairing the petrol grass cutter. Disconnect
ignition plug wire (35) (fig. K) from the ignition plug to
prevent accidental start up of the engine.
Be careful, the blade for cutting off the cutting line is
dangerous. When the petrol grass cutter is not being used, the
blade should always be secured.
REPLACEMENT OF CUTTING LINE SPOOL
Ensure the engine of petrol grass cutter is switched off.
• Use hexagonal key to lock spindle lock hole (23) (fig. E) and
unscrew cover of spool with cutting line (15) (fig. B).
• Hold spool cover firmly.
• Press in safety catches (18) at both sides of cover of the spool
with cutting line (fig. C).
• Remove spool with cutting line (19) (spring (20) should stay in
cover of spool with cutting line) (fig. D).
• Clean inside the cover of spool with cutting line thoroughly,
remove all residues of ground and grass.
• Unwind both ends of the line from spool by approximately 15
cm.
• Thread ends of cutting line of new spool through cutting line
holes (21) in the spool cover (fig. D).
• Firmly push new spool with cutting line into spool cover.
• Install the spool cover and press in so it snaps (spool cover must
be fully seated and secured with safety catches).
AIR FILTER
Dirty air filter reduces power of combustion engine and causes
increase of fuel consumption. Clean the air filter after each 5 hours
of the grass cutter operation.
• Remove the air filter shield (42) (fig. O).
• Remove the air filter (41) (fig. O) from the air filter shield.
• Wash the air filter in warm water with soap.
• Dry and install the air filter.
Do not wash the air filter in petrol or any other flammable
solvent to avoid fire hazard or appearance of dangerous
vapours.
FUEL FILTER (CLEANING / REPLACEMENT)
• Unscrew the fuel filler plug (6).
• Use wire hook or hexagonal key to remove the fuel filter (37)
(fig. M) through fuel filler hole.
